Abstract：
Using the three schemes for the spin assignment of rotational bands,the superdeformed bands of even-even nuclei observed in the A～190 region were analyzed.For the yrast SD bands ¹⁹⁴Hg(1)and ¹⁹⁴Pb(1),the spin assignment are consistent with the experimental results.The spin assignment for the other SD bands in even-even nuclei(A～190)are also believed to be reliable.Otherwise,the validity of the available theory should be re-examined when applied to the superdeformed nuclei.
